Hamilton's Trusted Roofer Since 2006
Bosani Roofing has protected 5,000+ Hamilton-area homes with GAF-certified craftsmanship, honest pricing, and work built to last through Ontario winters.
Two Decades Protecting Hamilton Roofs
Bosani Roofing started in 2006 with one goal: give Hamilton homeowners the same quality roof you'd put on your own house. No upselling, no shortcuts, no disappearing after the job is done.
Over 20 years, that commitment earned us GAF Master Elite Certification — held by fewer than 3% of roofing contractors across North America. It also earned us VELUX Certified status for skylight and sun tunnel installations, meaning your manufacturer warranty is protected when we install.
We serve Hamilton, Stoney Creek, Ancaster, Burlington, Grimsby, and surrounding communities. Every job is backed by full WSIB coverage and Ontario licensing.
📞 (905) 745-0818What to Expect Every Time
Honest Assessment First
If your roof can be repaired rather than replaced, we'll tell you — even if the repair is half the revenue.
Written Quotes Only
You get a written scope, material list, and timeline before anything starts. No verbal estimates, no surprise invoices.
GAF Certified Materials
As GAF Certified Installers, we use GAF products that qualify for full system warranties — not just shingle warranties.
Clean Site, Every Day
We magnet-sweep for nails, remove all debris, and leave your property cleaner than we found it — every day of the job.
We Answer the Phone
Call (905) 745-0818. We don't disappear after the deposit clears.
Fully Insured, Always
WSIB coverage protects your family if anything happens on your property during work. Always ask for current WSIB clearance.
